            Bug ID: 25358
           Summary: objdump doesn't parse mach-o indirect stubs in
                    disassembly
           Product: binutils
           Version: 2.33
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: cand at gmx dot com
  Target Milestone: ---

When using objdump to disassemble Mac (x86_64 mach-o) binaries, I couldn't get
it to display the function names for indirect stub calls like on Linux, with
-r/-R or any of the -P options. However the -P options show objdump does have
the info, it's just not finding its way to the disassembly.

   100000de7:   e8 5c 26 00 00          callq  100003448
<__ZL20fixStringForCoreDataP11objc_object+0
x1a0>

Here 100003448 is in the stubs section, and with the info there and in other
sections objdump could show what function is being called.
